Recaptcha v2 is not strong enough. I am getting 50-100 spam registrations per day. I need something stronger to prevent these attacks. My understanding is by setting a score with recaptcha v3 you are able to more accurately recognize bots and stop them. Am I correct?

I got a 90% change of being human using recaptcha v3.
1. What percentage would you consider appropriate for humans?
2. What percentage do you think recaptcha v2 is actually using?
3. Suppose you a user is trying to register to your site and gets the value from the answer to question #1 minus 10%. What would you do with that user?
4. Can you provide a link to a piece of documentation that states that v3 is actually "stronger" than v2?

Maybe you can or someone else can see something in this data that I'm not understanding. It seems to be telling me that 93% of all requests are suspicious yet success rate is still very high, more than 200 successful submissions every day, I think about 90% of sucessful submissions are spam. Is there some additional setting for recaptcha v2 that needs to be enabled? Will recaptcha v3 be any more effective?
